EVERARD HOME MORGAN, OF DOVER, ENGLAND.

ELECTRICALLY- DRIVEN LQCOMOTlVE.

SPECIFICATION forming part of Letters Patent No. 466,180, dated December 29, 1891.

Application filed March 9 1891. Serial No. 384,343. (No model.)

To coZZ whom it may concern.-

Be it known that I, EVERARD HOME Mon- GAN, civil engineer, a citizen of England, residing at 18 Maison Dieu Road, Dover, in the county of Kent, England, have invented a new and useful Improvement in Electrically- Driven Locomotives, of which the following is a specification.

My invention relates to means of utilizing all the main parts of an ordinary locomotive, except the steam boiler and engine, for its conversion into a locomotive driven by electricity, as I shall explain, referring to the accompanying drawings.

Figure l is a side elevation, and Fig.2 is a plan of the under frame of a locomotive converted according to my invention into one electrically driven.

I retain all the main frame A, the drivingwheels W, their axles X, and springs S; also, the running wheels and axles B, if there are such. In the place usually occupied by the boiler and engine I place secondary or storage batteries 0 and a dynamo-electric machine D,worked by the electricity from these batteries. On the axis of the dynamo-machine I fix a pinion E, gearing with a wheel F upon a transverse shaft G, which I mount in suitable bearings on the frame A. On the shaft G, I fix cranks H, corresponding with the cranks M on the wheels W, and connect these cranks by connecting-rods K in addition to the ordinary coupling-rods L.

I have shown in the drawings two pairs of coupled wheels I; but obviouslywhen there is only one pair of driving-wheels and no coupling-rods L the connections of the cranks H to the wheel-cranks remain the same. I have also shown in the drawings the arrangement existing in many locomotives having outside cylinders and outside cranks and connecting- WVhen the cranks on the driving-axle rods. are inside, as indicated by the dotted lines N, I make the shaft G with corresponding cranks O, which are connected to N.

The batteries 0 may be inclosed under a roof, as shown, surmounted by a hood P, containing an electric light.

Instead of connecting the gear Eand F directly, they may obviously be connected through intermediate gear, according as it may be necessary to suit the speed of the driving-wheels to that of the dynamo-machine.

In cases where the electricity is supplied from a conductor extending along theline the storage-batteries C may be dispensed with.

Having thus described the nature of this invention and the best means I knowof carrying the same into practical effect, I claim The combination, with the ordinary frame and drive-wheels of a locomotive, of a storage-battery O and dynamo D, arranged in the space usually occupied by the boiler and engine, a pinion E on the axis of the dynamo,a transverse shaft G, provided with a pair of cranks and a gear-wheel F, engaging the pinion on the axis of the dynamo, the cranks M on the axle of the driving-wheels, and the connecting-rods K between the cranks on the transverse gear-wheel shaft and the cranks on the axle of thedriving-wheels,substantially as described.

In testimony whereof I have signed my name to this specification, in presence of two subscribing witnesses, this 21st day of February, A. D. 1891.

EVERARD HOME MORGAN.
